Home Renovation Tip: Use A Fast Seal Compound To Seal Cracks in Cement Walls

When it comes to renovations, many home owners think that plastering cracks in walls is an easy job. For those with a lot of experience it is, but for those who don’t actually do professional renovations, it’s not that hard to mess something up.

Since we get plenty of requests for renovation tips, we decided to put together a video showing the right way to ad new plastering to cracks in cement walls. This way you don’t always need to call a renovation company for small jobs and could do it on your own the right way.

So what we had in this situation was a lot of moisture buildup in the cement wall just underneath the main room window. If your window wasn’t properly installed or has become lose with time, you can expect moisture to eventually seep through. The problem with a situation like this is that no matter how diligent you are about keeping the area dry, the moisture will still eventually seep in under the base of the window frame.

This is where stripping the wall of paint and adding the new plaster comes in. There’s a right way and a wrong way to apply plaster to cracked walls and right and wrong products to use.

Watch the video to see how it’s done.

Steps to plastering cracks under windows yourself

The very first thing you’re going to want to do is make sure the area that you’re plastering under the window is extremely clean. A good mixture of water and vinegar will do the tricks.

The next thing you’re going to need to do is grab your vacuum and vacuum out the entire area of the crack and in the crack too. This ensures there’s no left over debris that will get mixed into the plaster.

By now you’ve got your fast set compound which will seal the crack and deter it from ever coming back. 

To apply the compound plaster properly, the surface has to be clean.

The most optimal course of action after moisture leaks

When it comes to windows you have to courses of actions you can take to resolve moisture issues. One is to apply new plaster every now and then (usually when the crack reappears), or to have your window replaced with new ones. Today, new windows are extra beautiful but more importantly they are designed especially stronger than older windows and will definitely keep out the elements and reduce moisture entry into the home substantially.
